Screw this MAF-T!

[SonySlave]

Ok, so I'm badly overrunning my stock 1G MAS right now. MAS signal goes nuts after about 5k yadda, yadda... So I bought a MAF-T v.2.02 and GM sensor from a local a little while back.

I hooked it up in drawthrough since my UICP for my FMIC isn't meant for it. Idled great, no issues there but everytime I would go above 25% throttle, the car would hesitate and miss really bad and my wideband would skyrocket lean. I checked the box and the red light was flashing 2 times, which from the manual means no MAF signal was detected, yet it was idling fine still. Unhooked, and rehooked, same problem. I asked Full Throttle Tech and they said to check my wires and/or get a new sensor. All of the wires looked fine. So I went to NAPA and did a core exchange for a brand new GM sensor. Tried it again, same problem...

All I want to do is be able to run a decent amount of boost without my AFRs going crazy up top because the damn MAS signal is going crazy. I'm about to go throw this MAF-T into a river and go with a 2G MAS. I just really don't want to have to upgrade again if I ever overrun the 2G MAS in the future.

HELP PLEASE?

Showing that you have DSMLINK installed. Once V3 gets released it will have speed density as an option. No more need for a MAF-T or MAS. So if expect to over run a 2G MAS within a year stick with the MAF-T.

all the settings are correct, like mafs size 3 or 3.5 inch , base fuel injectors size and all that? and to be honest im not totally sure about why its not getting a mafs especially if its a brand new sensor.

i ran the maft for almost 2 years never had any problem like that.

Same thing happened to mine, tried three different mafs, had no luck, I gave up on if for now. I was gonna send it back to full throttle for them to look at it but never got around to it. I think I'm just gonna sell it. Kinda pissed me off b/c it cost me a few hundred between everything and its just sitting in my room.

Agreed. I'm in a bit of money also and I don't like spending money on something that won't work.

I have all of the setting correct in the box. I have dipswitches 1 and 2 down (OFF) for 3" MAF, and 3 and 4 are down (OFF) also. To mimic 450s, I have the AUX dial at 0 and the BASE dial at 2. All of the other dials are 0. Green LED is constantly dim like it should be and bright when I hit the throttle. And the red LED will stay off, but when I hit 25%+ throttle, the red light will start flashing twice. I don't get it.

I have a PTE 50-trim as you can see from my modlist. So I don't necessarily think I'll be making much over 400hp, if at all. So a 2G MAS would work for me I think. But as I said, I don't want to upgrade again down the line...

sounds like just about every other seller on here. pass your junk on to someone else to deal with

well it's probably your translator or your wiring in that case...

Wait till Version 3 hits the market .. Speed density FTW!!!!!!!!!!! I've been so glad to get rid of MAF style sytems, they're great for light mods, but at a point they just become a paint ot deal with, especially when trying to work your way around having the OEM one.

I'm lost on these MAF-T's I don't even think they were around when i started tuning DSM's, i had looked at every option then just went full stand alone (mainly becuase i was haltech a dealer back then).

 

[turborebel]

I must be missing something. Do you have a DSMchip to compensate for your injector size. Why are you setting the MAF-T for 450s if you actually have 680s?

 

[SonySlave]

Honestly, this thread should just die. I had a DSMChip made for my 680s and I wanted to use my MAF-T to just mimic the stock injectors. But I could never get the MAF-T working properly, so I said screw it. Since I don't have DSMLink yet, I had to improvise. To be honest, my DSMChip never really worked well for me anyway. I have a gut feeling my injectors are in fact 580s, not 680s, because I was having to add a ton of fuel with my chip to get decent AFRs. I've never gotten the injectors flowtested and bought them used.

I just decided that I would go with a 2G MAS instead and I also threw in my stock EPROM chip back in as well and honestly with just a 2G MAS and S-AFC for tuning, my car has NEVER ran better. I am running 24psi falling to 21psi on my PTE 50-trim on 92 pump gas with timing in the low-mid 20s with 0 knock. It idles perfectly. It cruises perfectly. And it absolutely hauls ass at WOT!

In my case: 2G MAS > MAF-T

They have been saying v3 is coming out for 2 years now. So when is the date set. Because until there is a date, its never coming out.

I'm thinking of doing the same thing exept keep the DSMchip. The MAF-t may be to tricky for me but mine is a blow through which seems to help spool up.
